UPS Extended Batteries

UPS extended batteries have the ability to supply you with longer runtime periods, as they have an increased capacity and life length. UPS systems will have an improved runtime when the internal battery set has an increased capacity or if an additional battery set is connected to the system. A UPS extended battery usually comes in a self-contained battery extension cabinet or the set will require installation on site onto a battery rack or stand or into a battery cabinet. Browse our superb UPS extended batteries range below to find the right option for your workplace.
